  • the present invention relates to a method and a device for determining dimensional properties of a measurement object which has a multiplicity of geometric elements.
  • EP 2 738 515 A1 discloses a typical example of such a device in the form of a coordinate measuring machine.
  • the known coordinate measuring machine has a workpiece holder and a CCD camera which can be moved in three orthogonal spatial directions relative to the workpiece holder.
  • the CCD camera is part of a measuring head, with the help of which the position of selected measuring points on a measuring object can be determined relative to a reference coordinate system.
  • measurement point coordinates are usually determined for a large number of measurement points on a measurement object. Based on these measuring point coordinates, dimensional properties of the measurement object can then be determined, such as the diameter of a hole or the distance between two edges on the measurement object.
  • an automated measurement process is desirable so that a large number of test objects of the same type can be measured as quickly and reproducibly as possible.
  • the creation of an automated measurement process requires basic knowledge of how coordinate measuring machines work and experience in how different geometric elements can best be measured on a measurement object.
  • an optimal measuring process can vary depending on the type of measuring head and / or which axes of movement are available on a coordinate measuring machine.
  • a measuring head can be made with a non-contact sensor, such as the coordinate measuring machine EP 2 738 515 A1 , require a different measuring sequence than, for example, a tactile measuring head, ie a measuring head with a probe element that is designed to touch selected measuring points on the measuring object.
  • a tactile measuring head ie a measuring head with a probe element that is designed to touch selected measuring points on the measuring object.
  • EP 2 738 515 A1 suggests using a wide-angle surveillance camera in addition to the CCD camera on the measuring head.
  • the wide-angle surveillance camera is designed to take a bird's-eye view of the entire measurement object. This (further) image is shown on the display of an operator terminal, in order to make it easier for the operator to create an automated measuring process, taking into account and avoiding possible collisions between the measuring head and the measuring object.
  • the device offers EP 2 738 515 A1 however, no further support in the creation of a measurement process and the operator therefore requires in-depth knowledge and experience in order to create an optimal measurement process for a specific measurement object.
  • a test characteristic represents a dimensional property of a defined geometric element (measuring element) on a measurement object, such as the diameter of a bore, the roundness of a cylinder section or the position of such a geometric element in relation to the reference coordinate system.
  • CALYPSO In order to quantify an inspection characteristic for a geometric element, several measuring points on the geometric element generally have to be recorded, so that the quantification of an inspection characteristic can require the acquisition of several individual measured values.
  • CALYPSO creates control commands with which the measuring head for measuring the associated measuring points can be automatically controlled.
  • CALYPSO makes it easier for an operator to create the measurement process because the test characteristics generally correspond to information that the operator can see from a technical drawing of the measurement object.
  • CALYPSO is able to automatically recognize geometric elements with defined standard geometries, such as circles, cylinders, rectangles, straight lines, etc., if the corresponding measuring point coordinates are available from the geometric element for evaluation.
  • the operator To create an automatic measurement process, however, the operator must recognize and determine all test features on the measurement object in advance, i.e. The creation of the measurement process begins with the recognition and definition of all the necessary test characteristics when planning "at the desk". The operator must then assign all the geometric elements on the measurement object to the previously selected test features. The operator then carries out all the measuring steps that the device should later perform automatically with manual control.
  • CALYPSO already facilitates the creation of an automatic measurement process in this way, the operator still has to have considerable specialist knowledge and experience in order to create a meaningful measurement process. The knowledge and experience of the operator must include, in particular, the individual mode of operation of the coordinate measuring machine used in order to obtain a measurement process that delivers all measurement values with the desired accuracy in the most efficient way.
  • the company Keyence Corporation offers a measuring system under the name "Model Series IM", in which the creation of measuring sequences takes place via a symbol menu.
  • the operator first selects individual general test characteristics from a symbol menu.
  • the operator selects specific measuring elements on which the previously selected test features are to be determined.
  • the measurement values are recorded using silhouette images of the measurement object.
  • US 2010/0268355 A1 discloses a method and a device for programming a coordinate measuring machine according to the preambles of claims 1 and 10.
  • a polygonal grid model of the object to be measured is created from a point cloud.
  • Measuring elements and an object coordinate system are determined using the grid model.

  • US 2010/0138028 A1 describes a method in which you can drag figures created with a graphics program onto an image of a measurement object in order to initiate the measurement of features.
  • US 2010/0060903 A1 discloses two variants for measuring a measurement object.
  • all features are measured fully automatically as soon as a workpiece to be measured has been identified on the basis of its properties as a fundamentally known measurement object. An individual operator selection is not provided.
  • the operator is offered sample shapes for selection based on thumbnails . As soon as the operator selects a sample form, all associated measurement steps are adopted in a measurement process.
  • EP 2 801 876 A1 discloses a graphical user interface for programming a measuring sequence, wherein it is possible to individually edit repeated partial sequences, for example for measuring adjacent bores.
  • WO 03/044452 A1 discloses a hand-held coordinate measuring machine and a method for guiding the operator during a measurement.
  • the operator can carry out a measurement and enter so-called GD&T data for a tolerance determination.
  • the measured values and the GD&T data are merged. If the operator wants to apply GD&T data to features that have already been measured, he must select the required features from a list of the available measurement results.
